摘要： A diffraction optical element comprises a substrate, a diffraction grating formed on the substrate with a material with low ultraviolet resistance and an ultraviolet screening means arranged on the substrate at a position closer to the incident light receiving side of the optical element relative to the diffraction grating. The ultraviolet screening means comprises a dielectric multilayer film and is formed on the other side of the substrate than the side carrying the diffraction grating. Alternatively, the ultraviolet screening means may be provided as a separate member from a diffraction optical element and arranged at a position closer to the incident light receiving side of the diffraction optical element in an optical system.

摘要： It is possible to produce a pigment-modified cyclodextrin film or fiber expected to be versatile in medicines, foods and pesticides such as packing films like wafer (for example, films to wrap food or drugs, and packages whose colors change when contained food begins to leak). It is comprised by p-methyl red of pigment-modified cyclodextrins, each made by modifying α-cyclodextrin with p-methyl red, having a structure to be included into different α-cyclodextrin of pigment-modified cyclodextrins than the p-methyl red, which leads the pigment-modified cyclodextrins to be highly associated between their molecules to form molecular aggregates.

摘要： An optical low-pass filter includes an optical member formed of a material capable of absorbing light in a particular wavelength range, e.g., an infrared range. The optical member has a plurality of ridge-like portions formed on at least one surface thereof at a predetermined pitch. The ridge-like portions comprise a phase type diffraction grating which has a low-pass filtering effect with respect to bundles of optical transmission rays passing therethrough.

摘要： A mold used for press-molding precision parts, such as an optical element formed of glass. A carbon film is formed at least on the molding surface of a matrix of the mold via an intermediate layer or without such a layer. The carbon film is shaped with a carbon ion beam having a desired ion energy such that a plurality of projections having an average height of from 0.5 to 30 nm are arranged at an average pitch of from 5 to 30 nm. Such a shape of the carbon film decreases the surface energy and frictional coefficient of the film and increases adhesion strength of the film to the matrix without impairing the surface roughness of an optical element to be molded. Thus, a resultant mirror surface of the mold is highly durable, free from film peeling and cracks in the formation of glass.
